Curved Scrapers Juneau AK

Here's the inside scoop on those inside curves. It's a lot easier to get good results if you concentrate on creating a hook on one side only. Here's how it works: Start by creating a slight bevel on the edge (Photo 1). Then remove the wire edge (Photo 2). Finally, use your burnisher to roll the cutting hook (Photo 3).

Sharpening Curved Scrapers

Q. I'm struggling to get a good cutting edge on my concave card scraper. Any tips?

A. Here's the inside scoop on those inside curves. It's a lot easier to get good results if you concentrate on creating a hook on one side only. Here's how it works: Start by creating a slight bevel on the edge (Photo 1). Then remove the wire edge (Photo 2). Finally, use your burnisher to roll the cutting hook (Photo 3).

PHOTO 1:File a slight bevel on the curve. With the scraper held in a vise, push a chainsaw file at a slight angle until you feel a continuous wire edge on the high side of the bevel.

PHOTO 2:Remove the wire edge with a super-fine diamond paddle. Because you have created a beveled edge, the wire edge will only form on the high side of the bevel.

PHOTO 3:Use a burnisher to roll the edge and create the cutting hook. Hold the burnisher almost flat and use firm pressure to form the cutting hook. A drop or two of light machine oil helps.
